Scientists found a mysterious void in the Great Pyramid of Giza thanks to particle physics

A void secreted away in the largest pyramid in Giza has been revealed thanks to some space-age technology.

Scientists used cutting-edge imaging techniques to see how particles called muons behaved deep within the Great Pyramid, also known as Khufu’s Pyramid.

The behavior of those particles — which are created by cosmic rays zipping around Earth's atmosphere — revealed the 30-meter-long void in the structure, which is around 450 feet tall and more than 4,000 years old.
